Storm drains are the metal grates that are found on streets, often at corners and on the sides of curbs and gutters. The purpose of the storm drain is to help prevent flooding by diverting rainwater and melted snow off of the streets and other paved surfaces and into a natural body of water.
Although storm drains fulfill an important purpose, they can harm water quality. The rainwater that is directed into a lake or stream by the storm drains is not treated. The rainwater can pick-up substances along the way such as lawn chemicals, oil, other household chemicals like paint, and soap and wash it directly into the stream. This runoff can pollute our waterways, harm wildlife and degrade water quality.
